3. find the frequency in hertz to two significant figures and appropriate units
4. find the [hase angle
5. find the period
6.find Vrms
7. find the power that this voltage delivers to a 60(ohm) resistance
8. find the first value after t=0 that v(t) reaches its peak value
Find the sample space for the experiment: Drawing bolts from a lot of 20, containing one defective D, until D is drawn, one at a time and assuming sampling without replacement, that is, bolts drawn are not returned to the lot.
A PWM unit is set-up with a pre-scale factor of 128. If the PWMPER register is loaded with 34 and the PWMDTY is loaded with 3, what are the resultant values for the output period and pulse width
If a silicon diffusion is doped with phosphorus (donors) at a concentration of 0.6 x 10^17/cm^3, what is the concentration of holes in this piece of silicon per cm^3 Assume ni = 1.45 x 10^10/cm^3, n = 1000 cm^2/V-s, p = 400 cm^2/V-s
(a) If the excitation volatge Eo is equal to the terminal voltage ( 4kv ), what is the maximum real power which the motor can deliver without losing synchronism (b) What is the rotor pole shift in electrical degrees
determine the capacitance of a parallel-plate capacitor having plates 14cm by 30cm separated by 0.01mm. The dielectric has (epsilon)(r)=15
A random variable X is normally distributed with unknown mean u and unknown standard deviation sigma. Find u and sigma if it is known that the probability X is less than 10 is 0.6950 and the probability that exceeds 6 is 0.7939.
(b) Find and list all essential prime implicants of the F function. (c) Find the minimal two level NAND gate implementation of the F function. Find the gate input cost. (d) Find the minimal two level NOR gate implementation of the F function. Find th..
Store the arrival times in memory locations starting from $1000.(Do this is in C. Store the results in an array and don't worry about the speci c location of the results.)
A current source of value 2cos(2t) A is used to power a string of 2W lightbulbs. If you wanted to replace this current source with a DC one, but have the same power drop, what DC current should you apply (one decimal place needed)
Phase current - Neutral Grounded Assume that the load is star connected with the neutral grounded. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Calculate and plot the Phase a current Ia using Fourier techniques.
